过期策略不能在网格8.8.9中工作

Question

我有一个问题，而使用gridgain 8.8.9。当我指定CityKey时，我有CityKey和City对象。COUNTRYCODE作为关联键，过期策略无效。我将1000条数据放入缓存，键为CityKey对象，值为City对象，过期时间为1分钟。1分钟后，只删除了2个数据，然后我在visor中使用cache -scan命令，所有的数据都被删除了，但是如果我使用cache命令，数据将一直存在。如果我删除@ affinitykeymap注释上的CityKey。COUNTRYCODE，过期策略可能有效。我用gridgain 8.8.18做了同样的测试，过期策略一直有效。所以我想知道这是否是gridgain 8.8.9中的一个bug，如果不是bug，原因是什么，如何解决。

CityKey

import org.apache.ignite.cache.affinity.AffinityKeyMapped;
public class CityKey {
/** */
private int ID;
/** */
@AffinityKeyMapped
private String COUNTRYCODE;
public CityKey(int ID, String COUNTRYCODE) {
this.ID = ID;
this.COUNTRYCODE = COUNTRYCODE;
}
public CityKey() {
}
public int getID() {
return ID;
}
public void setID(int ID) {
this.ID = ID;
}
@Override
public String toString() {
return "CityKey{" +
"ID=" + ID +
", COUNTRYCODE='" + COUNTRYCODE + ''' +
'}';
}
public String getCOUNTRYCODE() {
return COUNTRYCODE;
}
public void setCOUNTRYCODE(String COUNTRYCODE) {
this.COUNTRYCODE = COUNTRYCODE;
}
public void assssssss(String sssss){
System.out.println(sssss);
}
}

城市

public class City {
private String NAME;
private String DISTRICT;
private int POPULATION;
public City(String NAME, String DISTRICT, int POPULATION) {
this.NAME = NAME;
this.DISTRICT = DISTRICT;
this.POPULATION = POPULATION;
}
public String getNAME() {
return NAME;
}
public void setNAME(String NAME) {
this.NAME = NAME;
}
public String getDISTRICT() {
return DISTRICT;
}
public void setDISTRICT(String DISTRICT) {
this.DISTRICT = DISTRICT;
}
public int getPOPULATION() {
return POPULATION;
}
public void setPOPULATION(int POPULATION) {
this.POPULATION = POPULATION;
}
@Override
public String toString() {
return "City{" +
"NAME='" + NAME + ''' +
", DISTRICT='" + DISTRICT + ''' +
", POPULATION=" + POPULATION +
'}';
}
}

GridGainTest

public class GridGainTest {
public static void main(String[] args) throws Exception {
ClientConfiguration clientConfiguration = new ClientConfiguration().setAddresses("127.0.0.1:10800");
IgniteClient client = Ignition.startClient(clientConfiguration);
// client.destroyCache("testcity");
ClientCacheConfiguration cacheConfiguration = new ClientCacheConfiguration().setName("testcity");
cacheConfiguration.setExpiryPolicy(new CreatedExpiryPolicy(new Duration(TimeUnit.MINUTES, 1)));
ClientCache<CityKey, City> city = client.getOrCreateCache(cacheConfiguration);
for (int i = 1000000; i < 1001000; ++i) {
City value = new City("henan", "a place", 1000000);
CityKey key = new CityKey(i, "hn" + i);
city.put(key, value);
System.out.println(i);
}
client.close();
}
}

这是网格增益遮阳板的输出。

很可能是已知问题。这可能与由于错误的关联和赋值而导致的对墓碑的不当处理有关。尝试最新的GridGain 8.8.18。问题是GG-34306 -修复了清除墓碑的问题.
